A check engine light or malfunction indicator lamp ( MIL ), is a tell-tale that a computerized engine-management system used to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.). Found on the instrument panel of most ...
Pre-charge. Peak inrush current into a high voltage capacitor upon power up can stress the component, reducing its reliability. Pre-charge of the powerline voltages in a high voltage DC application is a preliminary mode which limits the inrush current during the power up procedure. A high-voltage system with a large capacitive load can be ...
A Nio battery swap station at a carpark in Beijing. Battery swapping or battery switching is an electric vehicle technology that allows battery electric vehicles to quickly exchange a discharged battery pack for a fully charged new one, as an alternative to recharging the vehicle via a charging station. Battery swapping is common in electric ...
Memory effect. Memory effect, also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium rechargeable batteries that causes them to hold less charge. [1] [2] It describes the situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly ...
This electric car battery takes less than 5 minutes to charge. Olesya Dmitracova, CNN. July 1, 2024 at 8:59 AM. Nyobolt. A British startup may have found the answer to one of the frustrations of ...
Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. [1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing. [2]
Battery charger. Charging a 12 V lead-acid car battery. A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when ...
A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries to protect against electrical overload, overcharging, and may protect against overvoltage. [1] [2] This prevents conditions that reduce battery performance or lifespan and may pose a safety risk.
